Rockvine

This big vine is a steady-growing plant, with the largest known specimen reaching a length of 471 feet (143.6 meters) and growing as high as 101 feet (30.8 meters). It prefers to grow on rock formations.

It takes 14 months for the yellow-green stems to mature, by which point they can have a diameter of 4 inches (10 cm) and remain soft and fleshy.

The circular, soft leaves reach up to 2.8 feet (86 cm) in length. They are a shade of brown that gradient shifts to green at the top, and have irregular edges.

During late spring, the vine produces several giant orange flowers.
